## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 64/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 695 tokens (~115/item across 6 items; 6 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 78/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 33% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

### 2026-10-29 (score 67)

First indexed and scored.

## MCP tools (6)

### `search_products` (~107 tokens)

Search products

Find products by name or by category and spec filters; returns key specs and the best in-stock offer. Example: {"query":"puck screen","category":"puck_screen","limit":5}

Input parameters:

- `category` (string)
- `filters` (object): Needs category. Spec field -> exact value, e.g. {"material":"brass"}; an unknown field or value is an error listing the valid ones
- `limit` (integer)
- `query` (string)

### `get_product` (~94 tokens)

Get product details

Full specs with per-field confidence and source, every offer with verified time, 30/90-day price range, and the top fits per category with counts. Example: {"product_id":"breville-barista-express"}

Input parameters:

- `fits_limit` (integer): Fits listed per category (default 10; 0 = counts only). For one pair use check_fit
- `product_id` (string, required): Product id or slug

### `compare` (~113 tokens)

Compare products

Side-by-side spec table with offers and the fields that differ. Pass 2-10 product_ids, or a category with filters. Example: {"product_ids":["breville-barista-express","breville-barista-pro"]}

Input parameters:

- `category` (string)
- `filters` (object): Needs category. Spec field -> exact value, e.g. {"material":"brass"}; an unknown field or value is an error listing the valid ones
- `limit` (integer)
- `product_ids` (array)

### `check_fit` (~88 tokens)

Check fit

Does this part fit that machine? Returns a verdict with the rule id and version that decided it, or the missing fields. Example: {"subject_id":"lucca-puck-screen-58mm","target_id":"breville-barista-express"}

Input parameters:

- `subject_id` (string, required): Part id or slug
- `target_id` (string, required): Id or slug of the machine the part goes on

### `check_stock` (~68 tokens)

Check stock and price

Availability and price per merchant, re-verified live when the data is over an hour old. Example: {"product_id":"lucca-puck-screen-58mm","merchant_id":"www-seattlecoffeegear-com"}

Input parameters:

- `merchant_id` (string)
- `product_id` (string, required)

### `report_issue` (~104 tokens)

Report a data issue

Flag a wrong spec, price or fit verdict. Reports never edit facts; two independent reports mark a fact disputed. Example: {"entity_type":"product","entity_id":"breville-barista-express","field":"portafilter_mm","claim":"Breville lists a 54 mm portafilter for the Barista Express"}

Input parameters:

- `claim` (string, required)
